High above the old-growth trees of Alan Seeger Natural Area, on top of Broad Mountain, stands the Greenwood Fire Tower. At  2,376 ft, this point marks the highest spot along the Standing Stone Trail. This section is known as the Greenwood Spur, marking the most northern portion of the SST. The hike from Alan Seeger to the top of Broad Mountain is short, but very steep, so be ready for a climb!
